The act of forcing fecal matter down a shower drain with one’s toes after deficating in the shower. It may be an act of vengeance, inebriation, or necessity.
It was negative 30 degrees in Fairbanks Alaska, so when visiting my friend with only an outhouse I had no choce but to mashed potatoes.

Usually takes place after a heavy night of drinking. This is where the female will stop at nothing and is desperate to have sex. Completely neglecting the fact that you may have whiskey dick, she vigorous "mashes" her vagina into your penis in hopes of stimulating a flaccid erection

A sexual maneuver whereby a male inserts or "mashes" his soft penis into a woman's vagina. The penis then becomes erect, leading to the term "baked potato." This term comes from the song "Do You Love Me?" by The Contours. In the song, they sing "I can mash potato." Originally an arcane dance form, this term has taken on new meanings in the bedroom. This term was coined in a Minneapolis basement by three men playing ping pong.
Steve: You give her the mashed potato?
Mike: Nah, man. I was already hard.
Steve: Yeah, it's a difficult move. The only way to really do it is if it's the seventh time for sex that day.
Mike: Or you could not be into vaginas.
Steve: True

If them superstitious motherfuckers want to have that kind of party, I'm going to put my dick in the mashed potatoes.
